根据电力系统对超导储能（SMES）装置的要求,并针对中国电力科学研究院制备的YBCO和BSCCO超导储能磁体失超的特点,作者研制了一套数字式失超保护装置.该装置采用数字信号处理技术（DSP）进行算法实现,通过对失超触发事件进行处理来控制保护电路的动作;同时,进行人机界面的开发,用于监测工作环境、失超保护电路及超导磁体的工作状态.最终,该装置通过了SMES系统动模试验,从而验证了其有效性.
According to power system request for SMES device and the quench characteristics of SMES hybrid magnet fabricated by YBCO and BSCCO in China Electric Power Research Institute, the authors develoP the digital quench protection device. The digital signal processing technology is adopted to realize the algorithm. The protection circuit is controlled by handling the quench trigger affairs. Also, the human machine interface is developed which is used to monitor the working states of the working environment, quench protection circuit and superconducting magnet. Finally, the device has passed the SMES simulated dynamic experiment and the effectiveness is verified.
